AB Nutrition  support  is  a  significant  component  of  patient  care  for  hospitalized  patients,  particularly  in  the  critical  care  setting.  Critical  illness  is  often  characterized  by  a  hypermetabolic  and  systemic  inflammatory  response  including  increased  infectious  morbidity,  increased  length  of  hospital  stay,  multiorgan  dysfunction,  and  finally  increased  mortality.  Historically,  nutrition  has  been  a  secondary  or  supportive  part  of  the  care  for  critically  ill  patients  with  the  goals  of  preserving  lean  body  mass,  maintaining  immune  function,  and  averting  metabolic  complications  of  critical  illness  (blunting  the  catabolic  effect  of  critical  illness).  Recently  these  goals  have  evolved  to  focus  on  applying  nutrition  as  a  therapy  with  current  goals  being  to  attenuate  metabolic  response  to  stress,  prevent  oxidative  cellular  injury,  and  favorably  modulate  immune  response.1,2  The  importance  of  nutrition  support  as  a  therapy  is  becoming  more  readily  apparent  with  advances  in  evidence-based  medicine.  However,  there  are  many  factors  to  consider  when  determining  an  appropriate  comprehensive  nutrition  therapy  plan  for  each  critically  ill  patient.
